drug-eluting balloon versus drug-eluting stent for high bleeding risk angioplasty

Conditions: High Bleeding Risk; Coronary Artery Disease (CAD); Percutaneous Coronary Intervention (PCI)

Summary: randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (tlf) at 12 months in high bleeding risk patients undergoing elective coronary percutaneous intervention comparing limus-eluting balloon vs. limus-eluting stents.

drug eluting stents (des) are the devices of choice for coronary angioplasty, including in patients with high-bleeding risk. different studies have been done to determine which strategy improves bleeding outcomes without risking the benefit of stenting. different double anti-platelet therapy (dapt) durations in different devices have shown that it is safe to reduce dapt, with an increase in ischemic events but a better net clinical outcome. safety and efficacy of drug eluting balloons (deb) were proved when it was compared with bare metal stents (bms) in de-novo coronary lesions by presenting no events of target vessel closure after treatment. our hypothesis is that treating this group of high-bleeding risk patients with deb will be no-inferior in terms of target vessel failure at 12 months when compared with des for treatment of de-novo coronary lesions in high bleeding risk population, reducing incidence of significant bleeding events with dapt reduction.
